To all whom it may concern.-

Be it known that'I, ROY EARL CHEESMAN,

a citizen of the United States,'residing at La Fayette, in the county ofTippecanoe and State of Indiana, have invented a new and usefulCorn-Planter, of which'the following Y is a specification.

, wheels in ground-engaging position.

This invention relates to corn-planters, and among the objects are tosimplify and improve the construction and operation of this class ofmachines and to provide improved means for adjusting the framevertically, so as to support said frame upon one of two sets of wheels,one set being ordinary transporting-wheels and the other set beingprovided for the purpose of engaging the ground to provide power foroperating the movable parts of the machine when the latter is inoperation. I

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations, and modifications within the scope of theinvention may be made when desired.

In the drawings, Figure 1 is a top plan view, partly in section, of acorn-planter constructed in accordance with the principles of theinvention. Fig. 2 is a sectional detail View taken on the planeindicated by the line 2 2 in Fig. 1 and showing one of the operating- Fi3 is a side elevation showing the machine v ith the transporting-wheelsin ground-engaging position. Fig. 4 is a sectional detail View taken onthe plane indicated by the line 4 4 in Fig. 1. Fig. 5 is a detailelevation, partly in section, showing a portion of the main shaft oraxle of the wheels and of the gage-wheel attachment. Fig. 6 is aperspective detail of the marker-carrying frame. Fig. 7 is an edge viewof one of the operating-wheels 4 and related parts. Fig. 8 is a detailview illustratinga modification.

Corresponding parts in the several figures ters of reference.

This invention is applicable to various kinds of plantersthat is to say,to planters equipped with various mechanisms for dropping the seed. Inthe drawings the invention has been shown as applied to a conventionalcorn-planter of which 1 designates the main or wheel frame; 2 therunner-frame, which is hingedly connected with the main frame; 3, theshaft or axle, which is connected for rotation with the main frame, and4 4 the operating-wheels, which are fixedly secured upon the axle nearthe ends of the latter.

A pair of disks 5, which are of equal size and each of which ispreferably provided at its edges with circumferential flanges, as

mounted for rotation upon the axle adjacent to the inner sides of thesupporting-wheels and eccentrically with relation to the axle, saiddisks being securely connected with each other, as by means ofconnecting-bars 7, extending transversely beneath the frame of themachine. Securely connected with the bars 7 is a lever 8, havingconnected therewith a stop member 9, adapted to engage any one of aplurality of notches 10 in a segment 11, which is securely attached toone of the side members of the frame 1. Supported loosely for rotationupon the disks 5 are the transporting-wheels 12, thus named because uponthese wheels the machine may be transported from one pl ace to anotherwithout operating the movable parts of the machine.

It will be seen that by manipulating the lever 8 the position of thedisks 5 with relation to the axle journaled in said disks may bechanged, so as to raise or lower the axle and the related parts-namely,the operatingwheels and the main frame 1, both of which are permanentlyrelated to the axle. When the latter is raised, it follows thatthetransporting-wheels, journaled upon the disks 5, are lowered and thatwhen the parts are in this position the machine may be transported fromplace to place, the transportingwheels being freely revoluble upon thedisks 5. When, on the other hand, the axle is lowered, theoperating-wheels 4 4, connected with said axle, are brought intoearth-engaging position, while the transporting-wheels are indicatedthroughout by similar charac-' shown at.6 in Fig. 5 of the drawings, are

are elevated above'the ground. This relative position of the parts hasbeen illustrated in Fig. 2 of the drawings, and when the parts droppingmechanism.

' rotation with the latter.

In Fig. 1 of the drawings the seed-dropping mechanism is actuated by ashaft 13, supported for rotation upon the runnerframe and having asprocket-wheel 14, connected by a link belt 15 with a sprocket wheel 16upon the axle 3. This is an ordinary and well-known manner oftransmitting motion to and-operating the seed-dropping mechanism; but toindicate that other mechanisms may be equally well employed there hasbeen shown as mounted upon the axle 3 an ordinary tappet-wheel 17. Thishas in Fig. 8 of the drawings been shown in connection with a slottedspring-actuated link-rod 15, connected pivotally at its forward end witha crank 16, extending from the rodshaft 17, from which motion is derivedto actuate the seed-dropping mechanism.

The axle 3 carries a spur-wheel 18, (see Fig. 4,) adjacent to which isloosely supported a lever 19, having a stop member 20, oper able bymeans of a handle 21, whereby said stop member, which is normally out ofengagement with the spur-wheel, may be temporarily placed in engagementtherewith, thus enabling the axle to be partially turned, as may benecessary at the beginning of rows or at intervals during the planting,for the purpose of bringing the seed-dropping mechanism into properalinement. While the axle is thus being turned, the frame of the machineis preferably supported upon the transporting-wheels, inasmuch as theoperatingwheels are fixed upon the axle, as previously set forth.

F designates a rectangular frame including side members 22, the innerends of which are connected by clamping members 23, having recesses 24,whereby they may be adjusted loosely upon the end of the axleor, ifpreferred, upon the hub of one of'the supportingwheels. The outercross-bar of the frame F, which is designated 25, is provided at theends thereof with trunnions 26, whereby it is supported for oscillationin perforations 27 in the side members 22. The cross-piece 25 isperforated for the passage of a shaft 28, carrying at its outer end agage-wheel or marker 29 and at its inner end a head 30, provided with anotch or recess 31, adapted to engage a lug 32 upon the end of the axle,said recess and lug constituting a clutch whereby the shaft 28 may beconnected with the axle for posed between the cross-piece 25 and thehead 30, serves to force the latter normally in the direction of theaxle. The shaft is pro:

A spring 33, inter-.

vided with a collar 34 to limit its movement in the cross-piece 25 andthe marking-wheel 29 is obviously disposed upon the shaft at a properdistance from the adjacent operatingwheel to perform the function ofmarking the ground to indicate the course of the planter upon its returntrip.

The operating-wheels 4 are provided with equidistantly-disposedperipheral lugs, as 40, to indicate the points at which the seed isdropped into hills. These devices also serve as indicators for theoperator when the main shaft is turned by means of the lever 19 to astarting position.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.

The construction is simple and inexpensive and the device is efiicientfor the purposes set forth.
